You're applying a simplicity in logic that doesn't scale to the real world. The problem is, we have reasonably tight control on a lot of other safety-critical supply chains where the only way to get cheaper is to be straight up unsafe. That's why your brake pads don't need DRM. But the horse is out of the barn on batteries. For a myriad of reasons, lithium ion batteries just somehow flew under the radar long enough that now literal boatloads of fire hazards are landing daily and no one has been able to stem the problem. Thermal sensors can only do so much for a bad battery design if they're on the bike rather than the battery, this isn't an engineering problem, but the closest thing to an engineering solution is to completely disincentivize 3rd parties from making batteries over a certain size as far as your own product goes.

There is a reason that their are different safety standards to achieve - regardless if you have DRM or some nonname brand. What I mean is that with a rigorous check any battery no having a CE mark (here in Europe) or other type of certification then it can’t be imported. I believe there is a world where reputable battery brands make all sort of battery for Ebikes, vacuum cleaners etc that fit the device and have an appropriate mark. No need to have a price tag like the bike manufacturer just a plain good battery maker.

  I agree with you in principle but the predicate accountability mechanisms currently are not functioning as they should for certain imports. E-bike batteries pose an outsized risk, hence the NY DRM carve-out.
